I have a high pitch noise coming from the storage department under my Winnebago Vista 27N.
We are at a campground and fully hooked up. Tried unhooking power, turning off converter.
Sounds like an alarm for something. However all seems fine.
Can't hear in coach. Can only hear sound when we open storage compartments below. Any ideas??
Which compartment? Or which one is it loudest in? Your inverter should be in the large passenger side compartment in front of the rear wheels. Is it coming from the pressure release valve on the hot water heater?
The inverter, which is on the wall in the second compartment back on the passenger side, has fans that run whether the inverter is on or not. They also run in the plugged-in, current pass-thru mode, whenever they want to.
